Microcontrollers deliver high-speed data processing for a wide range of options

The group is based on the ARM Cortex-M4 core with an FPU. It combines high-performance analog circuits, a broad range of timers and communication channels, and is offered in a mixture of packages, from 100 to 177 pins, with onboard flash memory varying from 512kB to 1536kB alongside up to 194kB of RAM and 32kB of data FLASH that can be rewritten up to 100,000 times. Operating frequency is up to 160MHz, and the microcontrollers have an operating temperature range of -40C to +85C.

As well as high-precision analog circuits that include a 12-bit AD converter (up to 24 channels) with a 1μs conversion speed, and an 8-bit DA converter (two channels), the group includes two DMA controllers; a high-speed DMA controller and a multi-function DMA controller. Both achieve low power consumption and advanced functions, while including highly versatile peripheral circuits, such as serial memory interface (SMIF), UART, I2C, TSPI, timers, and support for large-scale systems.

The AD converter enables selection of two sampling periods with arbitrary channels, contributing to a reduction of impedance adjustment components in large-scale systems that need multiple sensors. A built-in interlinking function for timers, UART, and TSPI, and an ISD add to reduced loads in software processing.
